The CFA635 series of advanced display modules will be changing from the previous hardware revision 1.2 to the new hardware revision 1.5.

Reason:

As part of our continuous improvement, the processor and PCB layout have been changed to improve availability, manufacturability, and quality

Impact:

The revised CFA635 series has Wide Temperature (-20°C to +70°C) operating range. Part numbers have changed accordingly:
TMF series modules will become TML series.
TFE series modules will become TFK series.
YYE series modules will become YYK series.

The CFA635 series now supports a single FBSCAB. The SCAB is no longer supported:

All four fans may be used on serial (-KS) and logic level (-KL) modules.
Maximum temperature sensors is 16.

ATX power supply control functions previously supported by J8 on the SCAB are now supported by H1 on the CFA-635.

The power supply and backlight circuits have been improved:
The backlight driver is a constant current design-the backlight current and brightness are now insensitive to supply voltage variations.

The incoming power supply range is 2.5v to 5.5v, so the CFA635 can easily be used in 3.3v systems.

The yellow backlight of the CFA635-YYK series is redesigned to improve brightness.

Supporting firmware for the reactivation of the CFA635 family of modules.

Last revision:

1v6

Description:

The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The majority of the changes to the firmware have been in support of the RW1067 LCD controller and are transparent to the user interface. The changes to the CFA635 2v0 firmware:

For hardware changes related to this firmware update, please see PCN #10405

Command 12 (0x0C): Set LCD Cursor Style
Option 4 = inverting, blinking block is no longer supported. This option will result in a blinking underscore.

Command 22 (0x16): Send Command Directly to the LCD Controller
Any command sent specifically to the Samsung S6A0073 will need to be reviewed / modified for the commands / registers of the Rockworks RW1067. Please contact the Crystalfontz Engineering Support Team at support@crystalfontz.com for the RW1067 datasheet.

Fixes
Updates to timings and sequence of Serial interface power up to prevent possible corruption of data displayed

Reason:

When the CFA635 family was scheduled for End of Life (see PCN #10365) there was no replacement available for the Samsung S6A0073 LCD controller. The CFA735 family was designed as replacement for the CFA635, allowing a path for improved performance, graphics, and the ability for end users to write their own firmware to take advantage of the capabilities of the enhanced hardware.

After the development of the CFA735 family, the RW1067 was developed as a replacement for the Samsung S6A0073 LCD controller for Crystalfontz America, Inc by Rockworks (China).

Impact:

This announcement impacts all variants, interfaces, and part numbers that currently use the CFA635 family of modules. The CFA635 can continue to be used in current and future designs.

Recommendation:

Continue to order and build with the CFA635 as required by production schedules. Transition to the CFA635 1v2 hardware and supporting firmware should be a seamless process. Engineering samples for qualification for the revised CFA635 are scheduled to be available Q3 of 2012.

Availability:

Q2 2012
Review / Update customer Defined Part custom firmware

Q3 2012
New hardware and supporting firmware available for engineering samples
Estimated - Begin transition to 1v2 hardware as 1v1 hardware inventory is depleted
NOTE: We will not ship production orders of 1v2 hardware until the 1v1 inventory is depleted

Reactivation of the CFA635 family of modules with 1v2 hardware and supporting firmware.

Last revision:

1v1

Description:

The CFA635 family of modules is being reactivated with a new LCD controller chip, the Rockworks RW1067. The changes to the CFA635 1v2 hardware are as follows:

LCD controller changing from Samsung S6A0073 to Rockworks RW1067

Supporting driving circuitry between the LCD controller and the LCD glass has been updated to support the Rockworks RW1067

The PCB layout has been updated to support the Rockworks RW1067

Firmware updates to support the Rockworks RW1067 and functional improvements – See PCN #10406

The only changes to the CFA635 family are to support the Rockworks RW1067 controller. There are no other physical changes to the CFA635.

2011-10-06:
Effective immediately, Crystalfontz America, Inc is announcing the End of Life (EOL) for the CFA635 family of modules.

The CFA635 is a character based intelligent LCD module built around a Cypress PSoC® micro-controller and a Samsung S6A0073 LCD controller. Samsung announced the EOL of the S6A0073 at the end of 2007. After the announcement, Crystalfontz America, Inc began designing a replacement module and planned for continuing to manufacture and support the CFA635 family until a compatible replacement module was designed and available.

REVISED: 2011-12-15REVISED: 2012-03-19

Reason:

As part of our continuous improvement process, the engineering services group at Crystalfontz America Inc. is announcing the End of Life (EOL) to our CFA635 family of modules. This end of life is scheduled to take place at the end of 2012 Q2.

The CFA635 is being replaced with the first of a new generation of intelligent modules from Crystalfontz America, Inc. This new module is the CFA735 family. The CFA735 family has been primarily designed to be a replacement for the CFA635 family with a number of enhancements / improvements.

Impact:

This announcement impacts all variants, interfaces, and part numbers that currently use the CFA635 family of modules.

The CFA635 family is not recommended for new designs.

Recommendation:

Continue to order and build with the CFA635 as required by schedules. Plan on making transition to the CFA735 family of modules when available.
